Abstract (en)
An oriented electrical steel sheet according to an embodiment of the present invention includes, in a unit of wt%, Si at 1.0 wt% to 5.0 wt%, C at 0.005 wt% or less (excluding 0 wt%), Mn at 0.001 wt% to 0.1 wt%, Cu at 0.001 wt% to 0.1 wt%, S at 0.001 wt% to 0.020 wt%, Se at 0.001 wt% to 0.050 wt%, Al at 0.0005 wt% to 0.010 wt%, N at 0.0005 wt% to 0.005 wt%, and the remainder of Fe and inevitable impurities.The oriented electrical steel sheet according to the embodiment of the present invention satisfies Equation 1.16≤10×Mn+Cu/S+Se+0.02−Al/N≤20(In Equation 1, [Mn], [Cu], [S], [Se], [Al], and [N] represent contents (wt%) of Mn, Cu, S, Se, Al, and N, respectively.)
